Picked up a 1970? Mastercraft Skier a few days ago. It has a Chrysler Marine 340 with a BW 1:1. It had been painted a hideous shade of teal at some point in its life. It sits on its original trailer. The boat runs great, little to no vibrations. The 340 with straights that sits half above the water is crazy loud. It appears to be mostly original. Speedos appear to have been changed. I have stripped the teal off and will begin putting her back to here original red hull, white stripe, and white deck. I will keep everyone who is interested updated. Any input is appreciated. We have been digging around is the obscure places for a hull id number, still have not found anything. 1969 is on the casting of the engine. I was very shocked at the quality of the early wake on this boat. Any knowledge on these early boats is appreciated.
